New Outstanding Drill Results at Havieron Extend the Strike
Length of High-Grade Mineralisation
Greatland Gold plc (AIM:GGP), the precious and base metals
exploration and development company, is pleased to provide an
update on Newcrest's drilling campaign at Greatland's 100% owned
Havieron licence in the Paterson region of Western Australia.
Summary
-- Outstanding, high-grade results from Newcrest's drilling
campaign at Havieron significantly extend zones of high-grade
mineralisation to the north.
-- Step out drill hole HAD023 intersects high-grade mineralisation 300 metres north of HAD005:
o 107m @ 2.2g/t Au from 656m, including 21m @ 10g/t Au from 665m
(HAD023)
-- Newcrest has completed Stage 1 of the Farm-in Agreement
(US$10 million in expenditure) and has commenced Stage 2
(additional US$10 million in expenditure).
-- Six drill rigs to remain operational during the Australian
summer period (December - March), subject to adverse weather
conditions, with a planned two week shutdown over Christmas.
Gervaise Heddle, Chief Executive Officer of Greatland Gold plc,
commented: "These outstanding results significantly extend the
known limits of high-grade mineralisation, particularly to the
north. It has become clear that the size of the mineralised
footprint now significantly exceeds our initial expectations.
"We are very pleased by Newcrest's continued enthusiasm and
commitment to the project, and we look forward to providing further
updates on Havieron as drilling continues through the Australian
summer period."
Greatland notes the release of an ASX announcement titled
"Exploration Update - Havieron" by Newcrest Mining Ltd ("Newcrest")
earlier today which highlights "Drilling returns high grade results
at Havieron".
Final assay results for HAD019, HAD020, HAD021 and HAD025, and
partial assay results for HAD023 and HAD028, representing 6,652m of
drilling, have been received and are announced today.

results are awaited. HAD024 is at pre-collar stage and HAD027 and
HAD030 were stopped in the cover sequence.
Next Steps for Havieron:
-- Newcrest has commenced Stage 2 of the Farm-in Agreement
(additional US$10 million in expenditure).
-- Six drill rigs to remain operational during Australian summer
period (December - March), subject to adverse weather events and a
planned two week shutdown over the Christmas period.
-- Based on results to date, the trend of mineralisation appears
to be heading to the north-west. In order to test the extent and
continuity of the interpreted mineralised trend, Newcrest has
recently changed the orientation of drilling from E-W to SW-NE.
-- Baseline environmental studies have commenced and preliminary
work for metallurgical and geotechnical studies is being
conducted.
-- Further drilling over the next 9-12 months will target the
delivery of a maiden resource estimate for Havieron.
"There are many positive developments highlighted by these
results, but I would like to focus on two in particular. First, the
outstanding results from a significant step out hole, HAD023, which
intersected high-grade mineralisation (including 21m @ 10g/t Au,
0.74% Cu from 665m) over 300 metres north of one of Greatland's
early outstanding holes, HAD005, thereby significantly extending
the known limits of high-grade mineralisation", continued Gervaise
Heddle.
"Second, I would also like to draw investors' attention to the
multiple high-grade intercepts contained within these results
(including 10.6m @ 22g/t Au, 1.3% Cu from 764.9m (HAD025) and 32m @
9.2g/t Au, 0.67% Cu from 555m (HAD028)), all of which serve to
further boost our confidence in the potential for a significant
high-grade resource at Havieron within the next 9-12 months",
concluded Gervaise Heddle.

Background to Havieron and Farm-in Agreement with Newcrest
In March 2019, Greatland signed a Farm-in Agreement with
Newcrest Operations Limited, a wholly-owned subsidiary of Newcrest
Mining Limited (ASX:NCM), to explore and develop Greatland's
Havieron gold-copper project in the Paterson region of Western
Australia. Newcrest has the right to acquire up to a 70% interest
in a 12-block area within E45/4701 that covers the Havieron target
by spending up to US$65m.
Greatland's Paterson project covers more than 385 square
kilometres in the Paterson region of Western Australia and includes
the Havieron licence, the Paterson Range East licence, and the
Black Hills licence.
A regional map showing the Havieron licence area with regional
targets and adjacent landholdings can be found at:

Further Information on Newcrest Drilling and Operations at
Havieron
The Havieron Project is operated by Newcrest under a Farm-in
Agreement with Greatland. It is centred on a magnetic anomaly
located 45km east of Telfer. The target is overlain by more than
420m of post mineral cover. Newcrest commenced drilling during the
June 2019 quarter.
Final assay results have been received for HAD019, HAD020,
HAD021, HAD025 with partial results received for HAD023 and HAD028,
representing 6,652m of drilling. HAD019 was stopped at 530m
downhole and was not progressed due to revised targeting. HAD024 is
at pre-collar stage and two holes were stopped in the cover
sequence (HAD027 and HAD030), while assays are pending for multiple
holes (including HAD022, HAD026 and HAD029).
Hole HAD020 is a 100m step out to the west of HAD014 to test for
mineralisation beneath HAD005 and HAD014 (HAD014 - 75.3m @ 3.4g/t
Au from 816.6m). Assay results include:
-- HAD020: 122.9m @1.7g/t Au, 0.36% Cu from 673m
Incl 14.6m @ 9.1g/t Au, 0.48% Cu from 705m and
114.8m @ 0.84g/t Au 0.13% Cu from 809.2m
Incl 10m @ 3.4g/t Au, 0.01% Cu from 895m and
184.5m @ 0.81g/t Au 0.44% Cu from 1096.5m
Incl 27.2m @ 2.8g/t Au, 0.54% Cu from 1134m
Hole HAD021 is a 75m step out to the east of HAD013 to test for
high grade mineralisation between HAD013 and HAD017 (HAD017 - 45m @
7.1g/t Au from 1077m). Assay results include:
-- HAD021: 128m @ 3.4g/t Au, 0.44% Cu from 670m
Incl 13m @ 13g/t Au, 1.1% Cu from 770m and
110.7m @ 1.9g/t Au, 0.12% Cu from 1039.3m
Hole HAD023 is a 100m step out to the north of HAD015 and is the
most northern hole to be drilled on the project to date (HAD015 -
28m @ 0.96g/t Au from 979m). Importantly, results confirm the
presence of high grade mineralisation within broad intersections of
gold well north of previous drilling with assay results which
include:
-- HAD023: 107m @ 2.2g/t Au, 0.22% Cu from 656m
Incl 21m @ 10g/t Au, 0.74% Cu from 665m
Hole HAD025 is a west to east drill hole collared approximately
75m north of HAD005 (HAD005 - 128m @ 7.4g/t Au from 660m). Amongst
broad widths of significant gold mineralisation, high grade
intervals have again been delineated. Also of significance are
widths of strong copper mineralisation. Assay results include:
-- HAD025: 118m @ 0.99g/t Au, 0.08% Cu from 580m
Incl 12m @ 3.9g/t Au, 0.21% Cu from 612m and
39m @ 6.5g/t Au, 0.40% Cu from 764m
Incl 10.6m @ 22g/t Au, 1.3% Cu from 764.9m
Hole HAD028 is an east to west drill hole collared approximately
125m northeast of HAD013 and represents a significant step out to
the east (HAD013 - 36m @ 4.1g/t Au from 481m). Thick intervals of
high grade gold mineralisation are again reported. Assay results
include:
-- HAD028: 45.8m @ 6.8g/t Au, 0.51% Cu from 543.2m
Incl 32m @ 9.2g/t Au, 0.67% Cu from 555m
Additional drill hole information is presented in Appendix I and
tabulated drill hole intercepts are presented in Appendix II.
Combined with previously released results, these new analytical
results from drill holes HAD020 through HAD028 are considered
outstanding. Results confirm broad widths of gold mineralisation at
Havieron. Continuity of high-grade gold mineralisation continues to
be defined across the system and importantly, step out drilling
(HAD023) has broadened mineralised extents a further 100m north of
previously reported results (300m north of HAD005).
Drilling programmes at Havieron are ongoing with an additional
18 holes (HAD022, HAD026, HAD029, HAD031-HAD045) at various stages
of progress and further assay results are awaited.
Newcrest has provided notice to Greatland that Newcrest has
completed Stage 1 of the Farm-in Agreement (US$10 million in
expenditure) and has commenced Stage 2 of the Farm-in (additional
US$10 million in expenditure). Six drill rigs are to remain
operational during the Australian summer period (December - March),
subject to adverse weather events and a planned two week shutdown
over Christmas.
Based on results to date, the trend of mineralisation appears to
be heading to the north-west. In order to test the extent and
continuity of the interpreted mineralised trend, Newcrest has
recently changed the orientation of drilling from E-W to SW-NE.
Baseline environmental studies have commenced and preliminary
work for metallurgical and geotechnical studies is being conducted.
Further drilling over the next 9-12 months will target the delivery
of a maiden resource estimate for Havieron.
Mineralisation at Havieron is hosted by metasedimentary
(meta-sandstones, meta-siltstones and meta-carbonate) and intrusive
rocks. Gold and copper mineralisation is hosted in breccia, vein
and massive sulphide replacement styles, typical of
intrusion-related and skarn types of mineralisation. The main
sulphide mineral assemblage contains well developed
pyrrhotite-chalcopyrite and pyrite. Alteration assemblages
associated with mineralisation are
amphibole-carbonate-biotite-sericite-chlorite. Higher grade gold
zones (+10g/t Au) are often associated with
quartz/chalcopyrite-pyrite veining.

Notes for Editors:
Greatland Gold plc is a London Stock Exchange AIM-listed
(AIM:GGP) natural resource exploration and development company with
a current focus on gold, copper and nickel exploration
projects.
The Company has six main projects; four situated in Western
Australia and two in Tasmania. All projects are 100% owned by
Greatland.
In March 2019, Greatland signed a Farm-in Agreement with
Newcrest Operations Limited, a wholly-owned subsidiary of Newcrest
Mining Limited (ASX:NCM), to explore and develop Greatland's
Havieron gold-copper project in the Paterson region of Western
Australia. Newcrest has the right to acquire up to a 70% interest
in a 12-block area within E45/4701 that covers the Havieron target
by spending up to US$65 million.
Greatland is seeking to identify large mineral deposits in areas
that have not been subject to extensive exploration previously. It
is widely recognised that the next generation of large deposits
will come from such under-explored areas and Greatland is applying
advanced exploration techniques to investigate a number of
carefully selected targets within its focused licence
portfolio.
The Company is also actively investigating a range of new
opportunities in precious and strategic metals and will update the
market on new opportunities as and when appropriate.

Section 1 Sampling Techniques and Data
Criteria Commentary
Sampling techniques Diamond core samples are obtained from diamond drilling
in Proterozoic basement lithologies. PQ-HQ and NQ diameter
diamond core was drilled on a 6m run. Diamond core
was cut using an automated core-cutter and half core
sampled at 1 m intervals with breaks for major geological
changes. Sampling intervals range from 0.2 - 1.0 m.
Cover sequences were not sampled.
-------------------- --------------------------------------------------------------------
Drilling techniques Permian Paterson Formation cover sequence was drilled
using mud rotary drilling and Reverse Circulation drilling
(HAD023 only). Depths of cover typically observed to
approximately 420 m vertically below surface. Steel
casing was emplaced to secure the pre-collar.
Diamond drilling was advanced from the base of the
cover sequence with PQ3, HQ3 and NQ2 diameter coring
configuration.
Diamond core from inclined drill holes are oriented
on 6m runs using an electronic core orientation tool
(Reflex ACTIII). At the end of each run, the bottom
of hole position is marked by the driller, which is
later transferred to the whole drill core run length
with a bottom of hole reference line.
-------------------- --------------------------------------------------------------------
Drill sample Diamond core recovery is systematically recorded from
recovery the commencement of diamond coring to end of hole,
by reconciling against driller's depth blocks in each
core tray with data recorded in the database. Drillers
depth blocks provided the depth, interval of core recovered,
and interval of core drilled.
Diamond core recoveries were typically 100%, with isolated
zones of lower recovery.
Cover sequence drilling by the mud-rotary drilling
did not yield recoverable samples.
-------------------- --------------------------------------------------------------------
Logging Geological logging recorded qualitative descriptions
of lithology, alteration, mineralisation, veining,
and structure (for all diamond core drilled), including
orientation of key geological features.
Geotechnical measurements were recorded including Rock
Quality Designation (RQD) fracture frequency, solid
core recovery and qualitative rock strength measurements.
Magnetic susceptibility measurements were recorded
every metre. The bulk density of selected drill core
intervals was determined at site on whole core samples.
All geological and geotechnical logging was conducted
at Havieron site.
Digital data logging was captured on diamond drill
core intervals only, and all data validated and stored
in an AcQuire database.
All drill cores were photographed, prior to cutting
and/or sampling the core.
-------------------- --------------------------------------------------------------------
Sub-sampling Sampling, sample preparation and quality control protocols
techniques are considered appropriate for the material being sampled.
and sample Diamond core was cut and sampled at the Telfer core
preparation processing facility. Half core samples were collected
in pre-numbered calico bags and grouped in plastic
bags for dispatch to the laboratory. Sample weights
typically varied from 0.5 to 4 kg. Sample sizes are
considered appropriate for the style of mineralisation.
Drill core samples were freighted by air and road to
the laboratory.
Sample preparation was conducted at Intertek Laboratory,
Perth. Samples were dried at 105(o) C, and crushed
to 95% passing 4.75 mm, and the split to obtain up
to 3 kg sub-sample, which was pulverised (using LM5)
to produce a pulped product with the minimum standard
of 95% passing 106 <MU>m.
Duplicate samples were collected from crush and pulp
samples at a rate of 1:20. Duplicate results show an
acceptable level of variability for the material sampled
and style of mineralisation.
Periodic size checks (1:20) for crush and pulp samples
and sample weights are provided by the laboratory and
recorded in the Acquire database.
-------------------- --------------------------------------------------------------------
Quality of Assaying of diamond drill core samples was conducted
assay data at Intertek, Perth. All samples were assayed for 48
and laboratory elements using a 4-acid digestion followed by ICP-AES/ICP-MS
tests determination (method 4A/MS907). Gold analyses were
determined by 50 g fire assay with AAS finish (method
FA50N/AA).
Sampling and assaying quality control procedures consisted
of inclusion of certified reference material (CRMs),
coarse residue and pulp duplicates with each batch
(at least 1:20).
Assays of quality control samples were compared with
reference samples in AcQuire database and verified
as acceptable prior to use of data from analysed batches.
Laboratory quality control data, including laboratory
standards, blanks, duplicates, repeats and grind size
results are captured in Acquire database and assessed
for accuracy and precision for recent data.
Due to the limited extent of the drilling program to
date, extended quality control programs are yet to
be undertaken, whereby pulped samples will be submitted
to an umpire laboratory and combined with more extensive
re-submission programs.
Analysis of the available QC sample assay results indicates
that an acceptable level of accuracy and precision
has been achieved and the database contains no analytical
data that has been numerically manipulated.
The assaying techniques and quality control protocols
used are considered appropriate for the data to be
used for reporting exploration drilling results.
-------------------- --------------------------------------------------------------------
Verification Sampling intervals defined by the Geologist are electronically
of sampling assigned sample identification numbers prior to core
and assaying cutting. Corresponding sample numbers matching pre-labelled
calico bags are assigned to each interval.
All sampling and assay information were stored in a
secure Acquire database with restricted access.
Electronically generated sample submission forms providing
the sample identification number accompany each submission
to the laboratory. Assay results from the laboratory
with corresponding sample identification are loaded
directly into the Acquire database.
Assessment of reported significant assay intervals
was verified by re-logging of diamond drill core intervals
and assessment of high-resolution core photography.
The verification of significant intersections has been
completed by company personnel and the Competent Person.
No adjustments are made to assay data, and no twinned
holes have been completed. Drilling intersects mineralisation
at various angles.
-------------------- --------------------------------------------------------------------
Location of Drill collar locations were surveyed using a differential
data points GPS with GNSS with a stated accuracy of +/- 0.5m for
drill holes HAD019, HAD020, HAD021, HAD023, HAD025,
and handheld GPS with +/-3 m accuracy for drill holes
HAD028.
Drill rig alignment was attained using an electronic
azimuth aligner. Downhole survey was collected at 6-12
m intervals in the cover sequence, and every 6 to 30
m in diamond drill core segments of the drill hole.
At the end of hole, all holes have been surveyed using
a continuous gyro survey to surface (Axis Mining Champ
Gyro).
Topographic control is established from SRTM (1 second)
topographic data and derived digital elevation model.
The topography is generally low relief to flat, with
an average elevation of 265 m, within dune corridors.
All collar coordinates are provided in the Geocentric
Datum of Australian (GDA94 Zone 51S).
-------------------- --------------------------------------------------------------------
Data spacing The drill hole spacing ranges from 50 - 500 m in lateral
and distribution extent within an area of 1.5 square kilometres.
The current drill hole spacing does not provide sufficient
information for the estimation of a Mineral Resource.
Significant assay intercepts remain open. Further drilling
is required to determine the extent of currently defined
mineralisation.
No sample compositing is applied to samples.
-------------------- --------------------------------------------------------------------
Orientation Drilling of reported holes HAD019, HAD020, HAD021,
of data in HAD023, HAD025, HAD028 are oriented perpendicular to
relation to a central dolerite dyke. The dolerite dyke has a north-south
geological orientation, with drilling established on an east-west
structure orientation.
Drill holes exploring the extents of the Havieron Mineral
System intersect moderately dipping carbonate and siliclastic
sedimentary facies, mineralised breccia and sub-vertical
intrusive lithologies. Steeply dipping mineralised
zones with a north-south orientation have been interpreted
from historic and Newcrest drill holes.
There is presently insufficient information to confirm
the geological model or true thickness of mineralised
intervals.
-------------------- --------------------------------------------------------------------
Sample security The security of samples is controlled by tracking samples
from drill rig to database.
Drill core was delivered from the drill rig to the
Havieron core yard every shift. On completion of geological
and geotechnical logging, core was transported by vehicle
to Telfer core processing facility by Newcrest personnel.
High resolution core photography and cutting of drill
core was undertaken at the Telfer core processing facility.
Samples were freighted in sealed bags by air and road
to the Laboratory, and in the custody of Newcrest representatives.
Sample numbers are generated directly from the database.
All samples are collected in pre-numbered calico bags.
Verification of sample numbers and identification is
conducted by the laboratory on receipt of samples,
and sample receipt advise issued to Newcrest.
Details of all sample movement are recorded in a database
table. Dates, Hole ID sample ranges, and the analytical
suite requested are recorded with the dispatch of samples
to analytical services. Any discrepancies logged at
the receipt of samples into the analytical services
are validated.
-------------------- --------------------------------------------------------------------
Audits or Due to the limited duration of the program, no external
reviews audits or reviews have been undertaken.
Internal verification and audit of Newcrest exploration
procedures and databases are periodically undertaken.

Section 2 Reporting of Exploration Results
Criteria Commentary
Mineral tenement The Havieron Project is entirely contained within 12
and land tenure sub-blocks of E45/4701, which is 100% owned by Greatland
status Pty Ltd. Newcrest has entered into an Exploration Farm-In
(EFI) agreement with Greatland Pty Ltd and Greatland
Gold Plc effective 12 March, 2019, with Newcrest as
Manager of the Havieron Project. The Stage 1 expenditure
commitment of US$10mln under the Farm-in agreement
with Greatland Gold has been met and Newcrest has provided
notice that it wishes to proceed to Stage 2.
There is a current ILUA (Indigenous Land Use Agreement)
signed in December 2015 which extends to the Havieron
Project.
All obligations with respect to legislative requirements
including minimum expenditure are maintained in good
standing. The exploration tenement E45/4701 was first
granted 17(th) July 2017 for 5 years, expiring 16(th)
July, 2022.
------------------------ ---------------------------------------------------------------------------------------
Exploration Newcrest Mining Limited completed six diamond core
done by other holes in the vicinity of the Havieron Project from
parties 1991 to 2003. Greatland Gold completed drill targeting
and drilling of 9 Reverse Circulation (RC) drill holes
with diamond tails for a total of approximately 6,800
m in 2018. Results of drilling programs conducted by
Greatland Gold have previously been reported on the
Greatland Gold web site.
Drilling has defined an intrusion-related mineral system
with evidence of breccia- and massive sulphide-hosted
higher-grade gold-copper mineralisation.
------------------------ ---------------------------------------------------------------------------------------
Geology The Havieron Project is located within the north-western
exposure of the Palaeo-proterozoic to Neoproterozoic
Paterson Orogen (formerly Paterson Province), 45 km
east of Telfer. The Yeneena Supergroup hosts the Havieron
prospect and consists of a 9 km thick sequence of marine
sedimentary rocks, and is entirely overlain by approximately
420 m of Phanerozoic sediments of the Paterson Formation
and Quaternary aeolian sediments.
Gold and copper mineralisation at Havieron consist
of breccia, vein and massive sulphide replacement gold
and copper mineralisation typical of intrusion-related
and skarn styles of mineralisation. Mineralisation
at the prospect is hosted by metasedimentary rocks
(meta-sandstones, meta-siltstones and meta-carbonate)
and intrusive rocks of an undetermined age. The main
mineral assemblage contains well developed pyrrhotite-chalcopyrite
and pyrite sulphide mineral assemblages as breccia
and vein infill, and massive sulphide lenses. The main
mineralisation event is associated with amphibole-carbonate-biotite-sericite-chlorite
wall rock alteration.

Data aggregation Significant assay intercepts are reported as (A) length-weighted
methods averages exceeding 1.0 g/t Au greater than or equal
to 10 m, with less than 5 m of consecutive internal
dilution; and (B) length-weighted averages exceeding
0.2 g/t Au for greater than or equal to 20 m, with
less than 10 m of consecutive internal dilution. No
top cuts are applied to intercept calculations.
------------------------ ---------------------------------------------------------------------------------------
Relationship Significant assay intervals reported represent apparent
between mineralisation widths. Insufficient geological information is available
widths and to confirm the geological model and true width of significant
intercept lengths assay intervals.

Balanced reporting This is the fourth release of Exploration Results for
this project made by Newcrest. The initial Newcrest
release is dated the 25(th) July 2019. The second release
is dated the 10(th) September 2019. The third release
is dated the 24(th) October 2019. Earlier reporting
of exploration programs conducted by Newcrest and Greatland
Gold have previously been reported. Exploration drilling
programs are ongoing and further material results will
be reported in subsequent Newcrest releases.

Further work Further work is planned to evaluate exploration opportunities
that extend the known mineralisation. Initial drilling
conducted by Newcrest has confirmed higher grade mineralisation,
broadened mineralised extents defined by prior drilling
and extended the depth of observed mineralisation of
the Havieron prospect. The results of drilling to date
indicate the limits of mineralisation have been closed
off to the east, and south, and remain open to the
north, and at depth. Drilling programs at Havieron
are ongoing with 6 drill rigs currently in operation.

Drillhole Data
Havieron Prospect, Paterson, Western Australia
Reporting Criteria: Intercepts reported are Au >0.20ppm
(0.2g/t Au) and minimum 20m downhole width with maximum consecutive
internal dilution of 10m. Also highlighted are high grade intervals
of Au >1.0ppm (1g/t Au) or Cu >5000ppm (0.5%), and minimum
10m downhole width with maximum consecutive internal dilution of
5m. Au grades are reported to two significant figures. Samples are
from diamond core drilling which is PQ, HQ or NQ in diameter. Core
is photographed and logged by the geology team before being cut.
Half core PQ, HQ and NQ samples are prepared for assay and the
remaining material is retained in the core farm for future
reference. Each assay batch is submitted with duplicates and
standards to monitor laboratory quality. Total depth (end of hole)
rounded to 1 decimal place for reporting purposes.
